Intermuscular lipomas of the thigh region in dogs: 11 cases.

Abstract

Ten dogs with intermuscular lipomas in the thigh region were treated by surgical resection. The masses were located predominantly between the semitendinosus and semimembranosus muscles and involved the full length of the femur. These lipomas were not infiltrative but located deep between the fascial planes of the associated muscles. These tumors can appear similar to soft-tissue sarcomas in this location, but they can be differentiated by cytology and histology. Differentiation from an infiltrative lipoma is predominantly determined at the time of surgery. No tumors recurred in the median follow-up period of 17 months.
